Title: Semiconductor laser driving circuit
Inventor: FUKUDOME FUJITO
IPC: H01S5/062
Filed: 1990-02-28
Granted: 1994-02-01
Abstract: Abstract of the Disclosure A semiconductor laser driving circuit is arranged so that a predetermined number of transistors can be selected from a group of transistors disposed in parallel according to the characteristics of a semiconductor laser and the selected transistors are connected in parallel between the semiconductor laser and a current source.  An optimum current is allowed to flow through the semiconductor laser to cause it to generate a required light output.   Moreover, a collector current which provides the optimum characteristics flows through each of the selected transistors.   Therefore, an optimum high-speed response can always be realized irrespective of the magnitude of the driving pulse current of the semiconductor laser.

Abstract: A layer of material such as pavement or sheet ice coating the surface of a roadway is efficiently removed using apparatus that includes a longitudinal tube in a breaker assembly which is rotatably carried by a control frame beam that depends from an articulate hydraulic lift and tilt mechanism of a road grader.  Coaxially attached to the tube and uniformly distributed along its length, a number of retainer rings each carry several radially extended teeth that function to fragment the layer.  Each tooth includes a tip portion with a free end that penetrates and punctures the layer and a trailing divergent portion which enters the puncture and translates a linear force applied thereto into a radial outward force that fractures and fragments the side walls of each puncture when the breaker assembly is lowered onto the layer and a downward force is applied to each tooth as the breaker assembly rolls over the layer surface.

Title: Subcabinet movement initiator
Inventor: WARREN EDWARD L
IPC: E05B65/46
Filed: 1991-02-20
Granted: 1998-04-28
Abstract: A cam (103) and follower (107) are used to move a file cabinet drawer  (114)  out of the closed position toward the open position.  The cam (103)  is rotated by a motor (113) via a shaft (123) wherein the cam surface (115) translates the rotational motion of the  shaft  (123)  into  the  linear  movement  of  the follower (107).  The follower (107) is attached to the side of the file cabinet drawer (114) and moves the file cabinet drawer (114) forward enough so a user may open the file cabinet drawer without using handles.  A hook  (129)  is connected to the cam  (103)  through a flexible stem (131)  and locks the follower (107)  in place  disallowing  unauthorized  access  to  the  file cabinet drawer (114).   The hook (129)  rotates along with the cam (103) to unlock the file cabinet drawer (114)  when it has been selected for opening.   The follower (107) is forced under the hook (129), which will flex at the flexible stem (131), when the file cabinet  drawer  (114)  is  returned  to  the  closed position.  A controller (110) receives inputs, through a keyboard  (141)  and determines which file cabinet drawer (114) has been selected to be opened.

Title: Device operable with an excellent spectrum suppression
Inventor: WATANABE NOZOMU
IPC: H04B7/26
Filed: 1991-06-27
Granted: 1997-05-13
Abstract: In a device for use in processing a baseband input signal and a carrier signal into an envelope output signal, a processing unit (3) is supplied with the baseband input signal and the carrier signal and produces, as a produced signal, a modulated signal and a non-modulated signal one at a time in response to a burst control signal.  A waveform generating unit (2) is supplied with the burst control signal and generates a control signal.  An amplifying unit (4) is supplied with the produced signal and the control signal and amplifies the produced signal to make the envelope output signal represent an envelope of the produced signal and to produce the envelope output signal with an excellent spectrum suppression.  Alternatively, the processing unit may be supplied with the control signal instead of the burst control signal.

Title: Method and apparatus for cursor movement control
Inventor: HIDAKA KAZUYOSHI
IPC: G06F3/0481
Filed: 1991-07-25
Granted: 1998-12-22
Abstract: The constraint mode provided by this invention allows a user to move a cursor of a pointing device, such as a mouse cursor, just along lines and curves on a graphics screen. The user can select a point located on lines and curves correctly even though the pointing device is moved quite roughly.  The user can also select a point that divides a segment by an arbitrary ratio, or a point that divides the segment  into  a  plurality  of  equal  parts.   The  method basically comprises  the  steps  of  entering  a  signal  for pointing to a position on a display screen and determining a point on the display screen in response  to the entered signal.  A point is then determined on the graphics object near to that point determined on the display screen.   A cursor is thus displayed at the determined point on the graphics object.

Title: Decoding system for distinguishing different types of convolutionally encoded signals
Inventor: DENT PAUL WILKINSON
IPC: H04L1/00
Filed: 1992-02-07
Granted: 2002-04-16
Abstract: A decoding system discriminates between different types of communications traffic signals. Each type of traffic signal is encoded using a different error correction code. Plural, parallel decoders each decode a received traffic signal using a different decoding technique. Each decoding technique operates in accordance with one of the error correction codes. A quantitative measurement of the reliability of a decoded result is generated by each decoder. A comparison processor accumulates the quantitative measurements made by each decoder and compares the accumulated values. That decoder having the most reliable, accumulated value is selected to decode the current traffic signals. The remaining decoders are deactivated to conserve processing time.

Abstract: A passive optical network includes a head-end station (1) and a plurality of terminations (2). The terminations (2) are re-sponsive to control signals from the head-end station (1). The head-end station (1) is arranged to receive frames having a prede-termined bit rate and comprising signals transmitted by the terminations (2). Ranging pulses are transmitted from each of the ter-minations (2) to the head-end station (1) where the received ranging pulses are sampled at a high sampling rate greater than the predetermined bit rate. The data samples are applied to a processor (7) which determines the phase and amplitude of the ranging pulses and generates control signals for the terminations (2) to modify the phase or timing and amplitude of the transmissions from the terminations (2). A locally generated marker pulse may be applied to the incoming data frame before it is sampled in the head-end station (1), the marker pulse providing a phase and amplitude reference for use by the control processor.
